Residents of Houston’s county poured in $104,625,241 to candidates and PACs during the last election cycle. Surrounding counties also contained big donors, with Montgomery, Fort Bend, Brazoria and Galveston counties all seeing residents contribute more than $1 million.

Harris County trailed the homes of New York City, Washington D.C., Los Angeles and Las Vegas, while beating out Chicago’s Cook County, Fairfield County, Conn., Dallas County, Middlesex County, Mass. and Palm Beach County, Fla.

In Texas’ other major markets, Bexar County contributed $20,448,600, Travis County contributed $25,094,539, Tarrant County contributed $20,630,673 and Dallas County contributed $94,915,252

The maps also illustrates other election trends, such as per capita giving, third party contributions and donations to each party, while allowing users to sort the data by two-year election cycle. In 2012 Harris County saw a per capita donation of $24.60, the highest in the region but well below less populated counties in the state, such as Borden, Midland and Donley counties.

Not surprisingly, the Houston area has been solidly Republican in recent presidential elections, but by selecting different year that maps shows varying support for each party.
